- Having this config for test environment allows to pre-populate default settings values in the settings table
- Right now the default-settings.json is an exact copy of the original "/data/schema/default-settings/default-settings.json". Having a starter file as an exact copy, allows to track the differences between environments as they are introduced easier

- To be able to reliably start ghost instance without a frontend the process needs access to urls/resources caches
- Storing the configuration in "paths" for now as there's no better place for it untill we are able to mock the content folder in pre-boot
* moved `server/config` to `shared/config`
* updated config import paths in server to use shared
* updated config import paths in frontend to use shared
* updated config import paths in test to use shared
* updated config import paths in root to use shared
* trigger regression tests
* of course the rebase broke tests
